Federalism did not fail in Somalia. but i can say that its not going as smooth as it should be,
because the Center aka (Xamar) does not want it to work, and is always trying to destroy it.
Federalism is not going smooth. It is suppose to be a joined power between states and central government. But a few states do not want to give up any power to the central government that federalism dictates. America had this problem few hundred years ago when they implemented federalism. Washington struggled with a few states that did not want to give up any power. Somalia is going through the same faze at the moment. I believe 90% of us don’t understand federalism.
